I guess the problem is that at this point, they can’t excise (all) the dumb bits - they’re locked in.
Gods know - he sounds kind of nuts, so extracting maximum money out of the company before being pushed out may have been an unintentional benefit after failing in an honest but insane attempt at world domination.
SoftBank itself is heavily reliant on debt. It is obsessed with debt financing, which means that, in order to make investments, it will take out loans against the equity it has on another company. SoftBank has taken unprofitable companies, pumped them full of borrowed money to turn them into larger, still unprofitable companies, and hoped that with SoftBank’s influx of cash, they can undercut market rates, monopolize an industry, jack the prices back up, and make off like bandits. We’ve seen this strategy with Uber, where SoftBank is the largest investor. And now we’re seeing it with WeWork. Failing monopolization, or basic business stuff like “making money,” SoftBank can at least keep up the smoke-and-mirrors long enough to do an IPO so it, a startup’s founders, and other early investors make a lot of money; later investors, employees, customers, and the public at large get screwed.
